What Causes a Car to Overheat?

A car is made up of various parts, all of which can cause problems if not properly maintained. One such issue that you should be aware of is overheating.

Low Coolant Levels

The primary cause of a car overheating is low coolant levels in the engine reservoir. This fluid plays an essential role in keeping your car’s engine running at a safe temperature. If there isn’t enough coolant in your vehicle, it cannot regulate itself correctly, and consequently, your car may overheat. It is necessary to check the level of your coolant regularly so that this does not happen to you.

To check your coolant levels:

• Park on leveled ground and let the engine cool completely.
• Find the coolant reservoir under the hood – usually located towards the front of the engine compartment. Readings will typically be between high and low marks denoted on the side of the tank.
• If your coolant levels are too low, add a 50/50 mix of water and antifreeze until it reaches the appropriate levels.

Faulty Thermostat

The thermostat helps ensure that your engine runs at the right temperature; that is, neither too hot nor too cold. It regulates the flow of coolant through the engine block and moves excess heat away from critical components. A faulty thermostat can fail “open,” thereby allowing coolant to continuously pass through without restriction. Alternatively, they might get stuck in the closed position, preventing any coolant from flowing and quickly causing the engine to overheat.

If your car is overheated, test the thermostat to see if it opens when heated:

• Remove the radiator cap with a cloth and allow the engine to warm up.
• Observe the coolant fluid in the radiator tank to see whether it rapidly moves after a few minutes.

If the thermostat isn’t opening, or you’re not sure if it is working correctly, contact your local mechanic for an immediate replacement.

Busted Radiator Fan

The radiator fan plays a significant role in keeping your engine’s temperature in check. If it fails, there isn’t enough airflow around the vehicle to reduce the excess heat produced by the engine block. A busted radiator fan comes as one of the most common reasons for overheating due to the way that it blocks the free flow of air through it. Motors actuate this component, but when they fail, your car may overheat even if everything else seems normal. Alternatively, fans could run slowly, causing limited cooling to occur.

To identify whether there’s something wrong with the electric radiator fan, do the following:

• Start the car’s engine when it has been cooling down for some time; let it idle and observe the speed at which the radiator blades are rotating.
• If the motor appears low or non-existent, it might be broken and should be fixed in no time.

“Most drivers who experience overheated engines ignore the fact until their vehicles stop running altogether,” says Brian Moody, executive editor of Autotrader.com. “A better practice is to pull over and turn off the engine before severe damage occurs.”

If your radiator fan has failed, replace it immediately. Failure to fix it can lead to more costly repairs in the future, perhaps necessitating complete engine replacements. Neglecting a failing radiator fan also places additional stress on other related parts like the head gasket, which could become damaged due to overheating.

How Far Can You Drive An Overheating Car?

This is an age-old question that does not have a definitive answer because it depends on the severity of your engine damage and underlying issues. Even if driving finesse later after noticing that your vehicle’s engine has begun to overheat can save you some money in the short-term, experts almost unanimously agree that this practice significantly worsens existing problems. So, avoid the mistake and pull over once you notice something abnormal with your car’s thermostat or overheating lights.

“If you continue to operate a heavily running hot motor,” warns ASE-Certified Master Technician Chris Latocki, “eventually the metal parts will cause distortion and lead to even more costly repairs.”

The bottom line here is always avoiding the likelihood of exposing your car too much longer time extensions than necessary to maintain its normal standard performance and keep up regular maintenance checks so that serious malfunctions don’t surprise you all along.

What Happens When a Car Overheats?

Overheating of a car engine is not uncommon and can happen due to various reasons such as extreme weather, low coolant levels, malfunctioning thermostat, or leaks in the cooling system. While some drivers may continue driving their overheating vehicle, it is not recommended as it can lead to significant damage to both the engine and transmission.

Engine Damage

An overheated engine can cause severe damage and eventually seize up if not addressed immediately. This happens because when the temperature rises above normal operating range, the metal parts expand beyond acceptable limits. Additionally, an overheating engine can cause cylinder head warping, cracked blocks, and blown head gaskets.

The heat generated by the engine can break down oil lubrication and create sludge that clogs up passages and causes congestion leading to additional complications. If ignored, these issues can result in costly repairs or even complete engine failure.

“Continued operation with an overheated engine will result in eventual engine failure, which can be far more complicated and expensive than resolving the initial problem.” – AAA

Transmission Damage

In addition to damaging the engine, an overheating vehicle can also cause significant harm to the transmission. The transmission operates at high temperatures under normal conditions and requires efficient cooling to maintain optimal working condition. An increase in temperature caused by engine overheating can cause seals and gaskets to leak fluid and even boil away, cutting down operations efficiently and causing permanent damage.

You might be able to drive your vehicle for a short distance after the engine has heated over its limit, but doing so repeatedly can lead to severe transmission problems, including metal erosion, warped parts, and worn-out clutches.

“Excessive heat can reduce the lifespan of a transmission and lead to costly repairs or replacement.” – AutoZone

While it might seem practical to keep driving the car until you reach your destination, it is not worth risking severe damage to the engine and transmission. It is important to recognize the signs of overheating and take immediate measures.

If you notice any temperature warning lights on the dashboard, clanking sounds coming from under the hood, if the hood itself feels extremely hot to the touch, or if there are any visible signs of fluid leaks, pull over immediately and turn off the engine. Letting the vehicle cool down before checking for coolant levels, radiator blockages, or calling for professional help can save you a lot of money in the long run.

The Bottom Line

An overheated car should never be driven for extended periods as it can cause significant damage to both the engine and transmission. The best course of action would be to shut off the engine immediately if you notice any signs of overheating and only continue after taking necessary precautions and remedying the issue. Keeping up with regular maintenance checks, including refilling fluids, changing oil filters, and monitoring internal temperatures, will go a long way in preventing the risk of overheating and avoiding expensive breakdowns later on.

How to Prevent Your Car from Overheating?

Maintain Proper Coolant Levels

One of the most important steps in preventing your car from overheating is by maintaining proper coolant levels. The coolant system is responsible for lowering the engine temperature and keeping it running optimally. Without enough coolant, your engine will quickly overheat and potentially cause damage.

To ensure that you have enough coolant, check the owner’s manual for the correct type of coolant recommended for your vehicle. Then regularly top off the coolant as necessary. If you notice that the coolant level drops frequently, there may be a leak in the coolant system which should be addressed immediately.

Regularly Check Radiator Hoses

Radiator hoses are an often overlooked aspect of car maintenance, but they play a critical role in keeping your engine cool. These hoses transfer coolant between the engine and radiator, so if they’re damaged or worn out, they can lead to significant engine problems.

To avoid this issue, make sure to regularly inspect the condition of the radiator hoses. Look out for cracks, bulges, or leaks and replace them immediately if any issues are found. It’s also a good idea to replace the hoses every few years even if they look fine, as they will wear out eventually due to age and use.

Check Your Thermostat

Your car’s thermostat regulates the flow of coolant through the engine based on its temperature. A malfunctioning thermostat can lead to inefficient cooling and potential overheating. To avoid this problem, regularly check your thermostat for functionality.

The easiest way to do this is by monitoring the temperature gauge on your dashboard while driving. If the engine seems to be running hotter than usual, it could indicate a faulty thermostat. Consider bringing your car to a mechanic for an inspection.

Keep Your Radiator Clean

The radiator is responsible for cooling the coolant as it passes through. Dirty or clogged radiators can restrict airflow, resulting in less efficient cooling and, eventually, overheating.

To keep your radiator working properly, make sure to regularly clean out any debris that may have become lodged between its fins. You can also perform a full flush of the radiator every few years to remove built-up sediment and ensure optimal performance.

Avoid Overexerting Your Engine

Your engine has a limit to how much heat it can safely handle. If you push it beyond this point by overexerting the car with heavy loads or driving too fast, it’s more likely to overheat.

To avoid this problem, be mindful of the load you’re carrying and maintain reasonable speeds when possible. In particularly hot weather, consider taking longer breaks to give your engine time to cool down.

Final Thoughts
